Memory
Memory is the basis for knowing your friends, your neighbors, the English language, the
national anthem, and yourself.
If memory was nonexistent, everyone would be a stranger to you; every language foreign; every task new; and even you yourself would
be a stranger.
The Phenomenon of Memory
Memory is any indication that learning has persisted over time. It is our ability to store
and retrieve information.
Studying Memory: Information Processing Models

Sequential Process
Information ProcessingThe Atkinson-Schiffrin (1968) three-stage model of memory includes a) sensory memory, b) short-
term memory, and c) long-term memory.

Modifications to the Three-Stage Model
• Some information skips the first two stages and enters long-term memory automatically.
• Since we cannot focus on all the sensory information received, we select information that is important to us and actively process it into our working memory.
Working Memory
A newer understanding of short-term memory that involves conscious, active processing of
incoming auditory and visual-spatial information, and of information retrieved from
long-term memory
Encoding: Getting Information In
How We Encode
1. Some information (route to your school) is automatically processed.
1. However, new or unusual information (friend’s new cell-phone number) requires attention and effort.
Automatic ProcessingWe process an enormous amount of information effortlessly, such as the
following:
1. Space: While reading a textbook, you automatically encode the place of a picture on a page.
2. Time: We unintentionally note the events that take place in a day.
3. Frequency: You effortlessly keep track of things that happen to you.
Effortful Processing
Committing novel information to memory requires effort just like learning a concept from
a textbook. Such processing leads to
durable and accessible memories.

Rehearsal
Effortful learning usually requires
rehearsal or conscious repetition.
Ebbinghaus studied rehearsal by using nonsense syllables: TUV YOF GEK XOZ
Hermann Ebbinghaus(1850-1909)

Rehearsal
The more times the nonsense syllables were
practiced on Day 1,the fewer repetitions
were required to remember them on Day
2.
Memory Effects
• Spacing Effect: We retain information better when we rehearse over time.
• Serial Position Effect: When your recall is better for first and last items on a list, but poor for middle items.
What We Encode
• Encoding by meaning• Encoding by images• Encoding by organization
Encoding Meaning
Processing the meaning of verbal information by associating it with what we already know or imagine. Encoding meaning (semantic encoding) results in better recognition later than visual or
acoustic encoding.
Visual Encoding
Mental pictures (imagery) are a powerful aid to effortful processing, especially when
combined with semantic encoding.
Showing adverse effects of tanning and smoking in a picture may be more powerful than simply talking about it.

Mnemonics
Imagery is at the heart of many memory aids. Mnemonic techniques use vivid imagery and
organizational devices in aiding memory.
Break down complex information into broad concepts and further subdivide them into
categories and subcategories.
Organizing Information for Encoding
1. Chunking2. Hierarchies
Chunking
Organizing items into a familiar, manageable unit. Try to remember the numbers below.
1-7-7-6-1-4-9-2-1-8-1-2-1-9-4-1
If you are well versed with American history, chunk the numbers together and see if you can recall them better. 1776
1492 1812 1941.
Chunking
Acronyms are another way of chunking information to remember it.
HOMES = Huron, Ontario, Michigan, Erie, Superior
ROY G. BIV = Red, Orange, Yellow, Green, Blue, Indigo, Violet

categories and subcategories.
